MINNESOTA J CATTLE sriinomon Application filed September To all whom it maya onoern-i' Be it-known that I, HAA EN P. Hanson, a citizen of the United States, residing at Albert Lea, inthe county ofFreeb'orn and State of Minnesota, .haveinvented a new and useful Improvement in Cattle Stanchions, of which-the followingris a specification;

This inventionrela-tes to cattle. stanchions. The object is to improve the construction of stanchions by the provision of simple means incorporated in theupper endsofthe side bars ofthe stanchion whereby the latter, when closed on the. neckof. the animal, may rotate. about a vertical longitudinal axis, and whereby one of the side bars may be swung outwardly on a pivot at the lower end thereof, to free the head ofj'the' animal or permit. entrance oftthe same, the said means limitingthe outward' novement oi the bar and supporting the same "when in open position, p f p a p In carrying. out the invention I providea slide bar mountedi'in the upper elbows. or heads of the side bars, said slide bar having stops at each terminal to arrest the opening movement. ofthe stanchion, and which, when the latter is closed, will automatically center itself in thesaid heads, so 'that the projectinghends. ofthe bar will be equal "on either sid'c-o't' the stanchion, the members of which are automatically locked'ltogether, by means independent of'the slide bar.

A. full and complete.understandingofthe invention maybe obtained from a consideration of the following detailed, description,

takenin connection with the accompanying drawing forming a part of this. specification, it being.understOodYthat while the drawing shows a practicalformof the in: vention, the latteris? not tobeconfined, to strict conformity with the showing thereof, but may be chan'gedor modified, so, long as such dianges or modifications.mark, no material departure from the salientfeatures of the invention, as specifically pointed) out. in the appendedolaims. p

The. cattle stanchion herein shown. and,

described is, in the main features, of; a. wellknowntype in common use on largestoclt. or dairy, farms 1 where. cleanliness, care and.

comfort of'the animalsiareof prime im-; portance,.the normally vertical and substantially parallel. side] bars. comprising. the stanch on, when closedabout the rIlBCkgQf an: anlmal, being. so secured and supported in position, as to, readily yield to the movement ofthe animal and[thus.eliminateall cause torfirritation, andat the same timeto hold the anima'lfin proper positionin the. stall whether. standingqup or lying. down,

,The present improvements are more, particularly, concerned. with the means for arresting; the 7 opening. movement of the bars comprising the stanchion, so as toprovide. for. the, maximum opening of the same. throughthe swinging. action of one ofithe. side bars while. the othen remains. in. its normal position, the. said' means: automati: cally stopping-themovable-side bar and at the same time permitting, the same to,be swung, upwardly to confine the. animal'or. release the same, and to beautomatically latched in closed position The means. for, accomplishing this purpose forms a g permanent part of the structure, and oflfers no ohstructions or projecting parts to. contact with or annoy; the animalyand when the stanchion is closed, the said'imeans -ijs automatically centeredwith respect toj the two stanchion bars so that the terminalsthereof are equally, project-ed either side ofthe' stanchion and :thus minimize. the possibility of interi ering with. the movements of the animal K-orswith. the duties vof. an attendant.

Refer-ring, tothe drawing, the. stanchion bars are designatedl and 2respectively, the bar 1, being substantially,stationar. While the, bar 2 is .adapted'to beswung upwardiand away fromthe bar: 1 at'the. upper. ends. Each. bar is composed of a channel iron. 3 having a longitudinally disposed" wooden filler 4, the fillers-4 being as is! customary, fdapted to contact with the neck. of, an animan;

At their lower ends, each bar 1 and 2 provided with'an inwardly directed elbow in the form of a suitable casting having a suitable flange for attaching the same to the channel irons 3," and the terminal of one elbow interfitting between the terminal of the other, and having suitable alined apertures for a pivot bolt 6, which permits the movable member to be swung from the closed position, shown in dotted lines in Figure 1 of the drawing, to the positionindicated in full lines therein, which is the maximum open position. In order to adapt the lower end of the stanchion to animals having smaller necks, aseries of perforations 7 are provided in the terminals of the lower elbows, in which the pivot bolt 6 may be inserted in an obvious manner, and

a flexible anchoring means in the form of two or three chain links 8 are preferably utilized for limiting the movementof the lower end of the stanchion.

The upper ends of the bars 1 and 2 are likewise fitted into inwardly directed elbows 9 and 10 respectively, each of which is'in the form of a channel; open at the top and having at theirouter ends'albottom wall 11 resting upon thetop endsoffthe fillers l, and each upper'elbow is also provided with an elevated, herizontal wall r12 located within the; channels and extending to the inner ends thereof. Between the out or walls'll and the higher, inner walls 12, there is provided a passageway 18, the outer ends of said walls 12 constituting abutments, and the space between the respective walls 11 and 12 providing a straight pas} sageway therethrough when the two stanchion bars are in closed position.

A straight, flat metal slide bar l l i sj stanchion is open, as shown in Fig. and

said slide bar then occupies an angular relation to the two elbows 9 and 10, the passageways 13 readily permitting such angular relation by reason of the wall 12 being arranged above the wall 11 in each elbow.

The slide bar 14 is provided, on its under side, with a plate 16, welded 01 other wise secured thereto, the ends of which constitute shoulders, one of which ends is adapted to be encountered by the inner edge of the wall 11 of the movable member or bar 2, which engagement causes the said bar to slide through the passage 130i the stationary stanchion member 1, until the opposite end or shoulder of the plate 16 encounters the inner edge of the wall 11 of the latter member, when the two members are closed and the inner ends of the elbows 9 and 10 are abutting, thus causing the slide bar 141 to project equally at each side of the stanchion, (Fig. 3).

The wall '12 of the movable member 2 is provided at its inner end with an inwardly projecting extension or finger 17, elevated abovecthe same and therefore in position to ride over the opposite wall 12 of thestationary member when thetwo are closed. Pivotally mounted above the finger 17is a gravity latch 18, the pivot of which has bearing in, the side walls'of the elbow 10 and the inner engaging end of the gravity latch is provided with a depending tooth 19, which is adapted to automatically look over an upstanding lug 20 formed at the outer end of the opposite wall 12 of the stationary member, to rigidly lock the two members of the stanchion together, as shown in Fi gure 3;

The elbow 9 of the stationary member 1 is provided'with upstanding ears 21 for the reception of a pin 22,-. which connects the stanchion to the depending link-23, swiv, elledin a well-known manner to a clamp 2 1, which is connected to a bar 25 located over the same and constituting part of a well-known arrangement in common use. i

From the foregoing it will be seen that simple and inexpensive means have been provided in cattle stanchions of this char acter, which serve to limit the outward or opening: movement of the swinging stanchion bar or member, and that the selfcentering features thereof are especially advantageous 7 iii permitting the maximum amount of space around both sides of the neck and headof the animal to allow room. for; the attendant; i

A special advantageousfeature of this device is the fact that the slide bar is not attached to either ofthe side bars of the stanchion nor to the suspension means but is slidable through both side bars, and when the stanchion is closed, the projection of the slide bar is equal on both sides. It not only limits the opening of the stanchion, but gives'support to the lower hinge in strength ening the stanchion when open.

lVhatis claimed is:

1. A stanchion comprising a relatively fixed side bar, a swingable side" bar, an. elongated slide bar passing loosely through the upper ends of the side bars and projectible beyondthe same, means for centering the slide bar so that it projects equally at each side of the stanchionwhen closed, abutments formed in each side bar adjacent to the slide bar, and lugs carried by the latter and adapted to engage the abntments to support the swingable side bar when fully opened.

2. A stanchion comprising a relatively fixed side bar, a swingable side bar, an elongated slide bar passing loosely through the upper ends of the side bars and projectible at opposite ends beyond the same, abutments formed in each side bar adjacent to the slide bar, and lugs carried by the latter at each end and adapted to engage the abutments to support the swingable side bars when fully opened, co-acting latch members carried by the opposite upper ends of the side bars above the slide bar and adapted to automatically lock the same together when closed, said slide bar acting as a guide to direct the latch members together, and projecting equally on both sides of the stanchion when the latter is closed.

3. A stanchion comprising a relatively fixed side bar, a laterally swingable side bar, said side bars having at their upper ends longitudinal channels formed of a hori zontal bottom wall, an elevated horizontal wall, and a horizontal passageway between said walls open at both ends, a latch mount ed above the elevated wall of the swingable side bar and carried thereby, a lug coacting with said latch provided on the elevated wall of the fixed side bar, and a substantially straight flat metal slide bar slidably mounted in said passageway and projectible through the same at each end beyond the said side bars when the stanchion is closed, said slide bar being provided with lugs at its ends adapted to engage the elevated wall when the stanchion is open so as to limit the opening thereof.

4. A cattle stanchion comprising a pair of side bars, means for hingedly connecting the bars to permit the swinging movement of one of the bars with reference to the other bar, coacting gravity latch members carried by the upper ends of said bars to automatically lock the side bars together when the swingable bar is closed, a slide bar having terminal lugs, abutments formed on the side bars at their upper ends engaging said lugs to support the swingable bar when the latter is open, and means to center the slide bar so that it is caused to project equally on both sides of the stanchion when the latter is closed.

5. A cattle stanchion comprising a pair of side bars, means for hingedly connecting the bars to permit the swinging movement of one of the bars with reference to the other bar, co-acting gravity latch members carried by the upper ends of said bars to automatically lock the side bars together when the swingable bar is closed, a slide bar having terminal lugs, abutments formed on the side bars at their upper ends engaging said lugs tosupport the swingable bar when the latter is open, and a central plate or enlargement provided on the underside of the slide bar to engage the side bars and center the slide bar when the stanchion is closed.

In testimony, that I- claim the foregoing as my own, I have hereunto aflixed my signature.
